In order for some of the CERN experiments to run you need to install cvmfs on Linux and Mac.

Script as instructed by LHC >

cd ~/
sudo dpkg -i cvmfs-release-latest_all.deb
rm -f cvmfs-release-latest_all.deb
sudo apt-get update
sudo apt-get install cvmfs cvmfs-config-default
sudo cvmfs_config setup
sudo wget -O /etc/cvmfs/default.local
sudo cvmfs_config reload
sudo sed -i '$ a\kernel.unprivileged_userns_clone = 1' /etc/sysctl.conf
sudo sysctl -p
sudo wget -O /sbin/create-boinc-cgroup
sudo wget -O /etc/systemd/system/boinc-client.service
sudo systemctl daemon-reload
sudo systemctl restart boinc-client

Statistics Export

LHC@home: Consent required to export statistics

Following the implementation of GDPR compliance with BOINC, user consent is now required to export BOINC statistics from LHC@home to BOINC statistics sites, such as BOINC stats .

To grant your consent, please login to the LHC@home site and update your project preferences. Once logged on to the LHC@home site, please navigate to the Project Preferences page.

Click on "Edit preferences" and then tick the box on the line:
"Do you consent to exporting your data to BOINC statistics aggregation Web sites?"

This will enable continued export of statistics from LHC@home for your BOINC user account. If you leave the box unchecked, statistics should no longer be exported.

Project Summary
Most of the scientific computing challenges that the LHC experiments are facing will require access to huge amounts of storage, the LHC will produce 15 Petabytes (15 million Gigabytes) of data per year. These data requirements mean that most analysis programmes cannot be run on individual PCs. This is why CERN is leading the development of Grid computing, which aims to link hundreds of major computing centres around the world.

However, there are exceptions where volunteer computing makes sense for the LHC. In particular, volunteer computing is good for tasks which need a lot of computing power but relatively little data transfer. In 2004, CERN's IT Department became interested in evaluating the sort of technology that is used by volunteer computing projects like SETI@home. LHC@home became the overall title for these efforts, and a program called SixTrack, which simulates particles traveling around the LHC to study the stability of their orbits, became the first application to be tested. It was chosen because it can fit on a single PC and requires relatively little input or output, but a lot of processing power.

Sixtrack began running as a volunteer computing project in 2004, and has been running for most of the time ever since. In addition, a new application called Garfield has been ported so it can run on the same BOINC platform as Sixtrack, and work is ongoing at CERN to see whether even more sophisticated physics software could be ported, especially using virtualization technologies.

The following applications are supported:

Please look at the web site as they change regularly.  In general Sixtrack is a CPU only application and all the rest use Virtualbox, except if you have a 64 Bit Linux machime there is a Beta CPU Multi Thread (mt) application for Atlas Simulation.
